1.1 Summary
NQB1, NQB2 standard type of quarter-turn electric valve actuators and NQB1.IN, NQB2.IN
integral type of quarter-turn electric valve actuators (hereinafter referred to as “Electric actuator”)
are the two models with small torque value in NQB detached series. This series is developed from
QB1, QB2. Thus, the performance of this series has improved comparing with that of QB1, QB2.
This series can operate with ball valve, butterfly valve and other kinds whose discs can only rotate
90°so as to control valve to open or close. In this case, pipe system automation control can be
achieved. Both single unit control and collective-remote control can be realized. Remote electric
control and manual operation, electric operation on site can also be realized. This series can be
largely applied in pipe and valve industrial field.
This Operation Manual is applied to Standard type and Integral type of electric actuator.
Additional instruction is offered if there is special function of electric actuator (eg.
Explosion-proof type of electric actuator). This Operation Manual, together with some Additional
Instruction, can help to ensure that product mounting, debugging and maintenance are dealt in
right ways.
Please refer to Fig.1-Fig.4 for product outline. For the dimension of the flange coupling with
valve, the dimension of driving shaft’s whole and key; refer to the Catalogue of the manufacturer.
(Notify the specific technical parameters when ordering.) Please refer to product’s nameplate for
driving output power of the electric actuator (Output speed, torque, etc.)
